Improving an outpatient clinic utilization using decision analysis-based patient scheduling

This study presents a predictive model to be used in scheduling patients in an urban outpatient clinic. The model is based upon actual patient characteristics from a physical therapy clinic within an urban health and wellness center situated in a public university. A number of reported patients' characteristics such as age, education level, distance from the clinic, historical attendance records, etc. were examined to determine if they significantly impacted the patients' missing scheduled appointments (no-shows.) Decision tree analysis was used to develop a model that assessed the likelihood of a patient's no-show, using key patient characteristics and attendance records. Such a model can be used to assist with scheduling patients in an outpatient clinic, while attempting to increase the clinic's overall utilization. Four tree growing criteria were examined to develop the model with the strongest predictive power. Predictive power of each method was assessed by using the entire dataset as well as using split sampling. The results were then compared with those of a Bayesian networks model and a neural networks model. In addition, the trade-off between the selected decision tree model's predictive power versus simplicity of the associated classification rules was examined. We also assessed the impact of various levels of overbooking on the clinic's utilization when using patients' schedules based on the predictive model.

Tourist Guides and Job Related Problems,Analysis and Evidence from Jordan

This study investigates the challenges that professional Jordanian tourist guides may encounter. The implication of this research stems from the fact that very little research, at least in Jordan, has addressed the problems that tourist guides encounter. Qualitative methods, using participants’ observations and in-depth interviewing methods, were used to generate insights from the collected data. The results reveal multiple critical challenges that impact the professional stability of tourist guides. Further efforts are required to fully understand the needs of tourist guides.

个体不健康影响因素研究

社会的急速发展和重大变化给人们带来了很多富足的物质条件和特殊机遇,同时也带来了各种新的挑战、压力与不适应。究其原因是多方面的,是遗传素质、环境、教育(特指学校教育)、个人主观能力性综合作用的结果。本文从这四个方面,就个人成长过程中主观意志与客观环境的影响作用进行深入分析。     

论英美法系国家的展示性证据

英美法系的展示性证据是一种有形证据,但不是一种实际存在的证据或事实,而是一种解说性证据,或者说律师用来提高举证说服力的证明方法。在法庭中使用展示性证据可以使自己的思想更容易被审理者理解和接受,尤其当涉及复杂的、技术性、科学性、数值性的案件。展示性证据包括图表、照片、摘要、模型、录像资料、事件的重建和演示等类型。展示性证据在开场陈述和结案陈词中都被律师广泛运用。     

多孔结构建筑材料力学性能的有限元分析

多孔材料是一种新兴的材料,制备较易,成本较低。相对于一般连续介质材料而言,多孔材料具有比强度高、比表面积高、相对密度低、重量轻、隔音、隔热等优点。它最大的特点是具有排列规则、大小可调的孔道结构,在建筑材料中也有很多的应用。因此,对非均匀孔洞与均匀孔洞建筑材料力学性能的研究是很重要的课题。论文通过建立非均匀孔洞和均匀孔洞的有限元模型,对比分析两种模型的受力性能,更好地进行多孔建筑材料的推广和使用。
